* intl/Makefile (CPPFLAGS): Change $(nlsdir) to $(i18ndir) in
LOCALE_ALIAS_PATH.
Fri May 3 03:14:02 1996 Ulrich Drepper <drepper@cygnus.com>
* intl/Makefile (routines): Add l10nflist and explodename.
(distribute): Add loadinfo.h and locale.alias.
(install-others): New variable to install locale.alias.
* intl/dcgettext.c, intl/finddomain.c, intl/gettextP.h,
intl/loadmsgcat.c: Adapt for upcoming gettext-0.10.13. Some code
is now shared with the locale implementation.
* intl/explodename.c, intl/l10nflist.c, intl/loadinfo.h: New file.
Extracted from finddomain.c. This is also used in the locale
implementation.
* intl/locale.alias: New file. Locale alias database compatible
with X Window System's locale alias file. Can now be used in
locale and gettext code.
* libio/stdio.h: Add prototypes for asprint and vasprintf.
* locale/C-collate.c, locale/C-ctype.c, locale/C-messages.c,
locale/C-monetary.c, locale/C-numeric.c, locale/C-time.c: Add new
field in structure with name of locale ("C" in this case).
* locale/Makefile (routines): Add findlocale.
* locale/findlocale.c: New file. Instead of trying to load the
directly described file we now try to be much smarter when this
fails. Use the same code as gettext does.
* locale/loadlocale.c, locale/setlocale.c: Rewrite to know about
new loading scheme.
* locale/localeinfo.h: Adapt prototypes and declarations for new
setlocale implementation. Remove definition of u32_t type. We
now use u_int32_t from <sys/types.h>.
* locale/programs/charset.h (ILLEGAL_CHAR_VALUE): Provide type
with constant.
* locale/programs/config.h, locale/lc-collate.c,
locale/localeinfo.h, locale/programs/ld-collate.c,
locale/programs/ld-ctype.c, locale/programs/ld-messages.c,
locale/programs/ld-monetary.c, locale/programs/ld-numeric.c,
locale/programs/ld-time.c, locale/weight.h, string/strcoll.c:
Change to use u_int32_t and u_int16_t.
* locale/programs/localedef.c (construct_output_path): Change name
of output locale to contain normalized form of the character set
portion.
* string/Makefile (routines): Add agrz-ctsep and argz-next.
(tests): Add tst-strlen.
* string/argz-ctsep.c: New file. Implement reverse operation
from argz-stringify.
* string/argz-next.c: Non-inline version of function from argz.h.
* string/argz.h, string/envz.h: Make usable as global header file.
* string/envz.c: Fix declarations to use size_t where prototypes
say so.
* string/tst-strlen.c: New file. Another test for critical
situation in strlen implementations.
* sysdeps/i386/i586/strlen.S: Fix bug with highest byte in word
being zero.
* wctype/test_wctype.c: Fix controlling comparison after change to
32 bit character class array.
Fri May 3 12:53:12 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* sysdeps/unix/sysv/linux/sys/socket.h: Remove spurious doubled line.
Thu May 2 22:50:52 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* sysdeps/unix/sysv/linux/getpriority.c: New file.
* sysdeps/unix/sysv/linux/syscalls.list: Add s_getpriority.
Thu May 2 22:41:31 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* sysdeps/unix/sysv/linux/m68k/fpu_control.h (_FPU_DEFAULT):
Disable all exceptions.
Thu May 2 22:33:14 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* sysdeps/m68k/fpu/e_acos.c, sysdeps/m68k/fpu/e_acosf.c,
sysdeps/m68k/fpu/e_fmod.c, sysdeps/m68k/fpu/e_fmodf.c,
sysdeps/m68k/fpu/isinfl.c, sysdeps/m68k/fpu/isnanl.c,
sysdeps/m68k/fpu/s_atan.c, sysdeps/m68k/fpu/s_atanf.c,
sysdeps/m68k/fpu/s_frexp.c, sysdeps/m68k/fpu/s_frexpf.c,
sysdeps/m68k/fpu/s_ilogb.c, sysdeps/m68k/fpu/s_ilogbf.c,
sysdeps/m68k/fpu/s_isinf.c, sysdeps/m68k/fpu/s_isinff.c,
sysdeps/m68k/fpu/s_ldexp.c, sysdeps/m68k/fpu/s_ldexpf.c,
sysdeps/m68k/fpu/s_modf.c, sysdeps/m68k/fpu/s_modff.c: Don't
define __NO_MATH_INLINES, which is already defined on command
line.
Thu May 2 22:18:28 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* sysdeps/libm-ieee754/e_j0f.c (__ieee754_j0f, __ieee754_y0f):
Replace 0x80000000 by 0x48000000.
* sysdeps/libm-ieee754/e_j1f.c (__ieee754_j1f): Likewise.
Thu May 2 21:30:33 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* sunrpc/svc_simple.c: Make global variable pl local to
registerrpc.
Thu May 2 00:24:04 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* time/Makefile (tz-cflags): New variable.
(CFLAGS-tzfile.c): New variable.
(CFLAGS-zic.c): Add $(tz-cflags).
(tz-cc): Remove variable.
($(objpfx)tzfile.o, $(objpfx)zic.o): Remove targets.
* sysdeps/mach/hurd/getcwd.c: Jump out of both loops when we find a
name, instead of checking for reaching end of buffer, which happens
when the match is the last entry in the buffer.
